Abstract: Les convoyeurs à vibrations de grandes dimensions connus ne conviennent pas pour transporter des matières en vrac ou des petites pièces dans un bain liquide, étant donné que le liquide (2), compte tenu de son incompressibilité, transmet les vibrations à d'autres composants, par exemple au réservoir (1) du liquide. Afin de résoudre ce problème, un espace compressible (9) agencé sous la partie en vibration (2) amortit les vibrations après avoir été adapté au bain de liquide. L'espace (9) est de préférence rempli de gaz et l'on peut modifier ses propriétés d'amortissement en amenant du gaz supplémentaire par un conduit (16) fermable par un organe (17) ou en évacuant une partie du gaz de remplissage par un autre conduit (18), lui aussi fermable par un organe (19).

Abstract: Pompe à piston (P) volumétrique jetable comportant un corps en polycarbonate (B), un piston (10), une soupape d'entrée (22) et une soupape de sortie (24). La soupape de sortie (24) est reliée à une chambre de sortie (28) qui est séparée de la soupape de sortie (24) par une membrane élastomère (18). La membrane élastomère (18) entoure une chambre d'accumulation (16) qui est remplie de fluide, par exemple de l'air sous pression atmosphérique. Les pulsations de pression de sortie dues aux coups de piston (10) sont amorties par l'effet flectionnel de la membrane élastomère (18), qui comprime le fluide à l'intérieur de la chambre d'accumulation (16). La pression d'éjection de la pompe est amortie et suffisante pour traverser des cathéthers d'angioplasie (A) de très faible section transversale traversés par des lumens de perfusion (42). Cette pompe (P) est combinée avec un cathéther d'angioplasie (A) de très faible section à ballonnet, ce qui permet de fixer le cathéter sur un passage extrêmement étroit et de pomper un volume suffisant de sang à travers ce cathéter de faible section lorsque le ballonnet est gonflé.

Abstract: A multiple input CMOS logic circuit includes a bistable input section with two nodes N1, N2. In an inactive state, the input section maintains the nodes at opposite CMOS logic levels. In an active state, the nodes are maintained at substantially equal levels positioned between the two CMOS logic levels. The input section includes a set of parallel CMOS transistor pairs T1, T2, T3, T4, cross connected at the nodes, and unbalanced by inequality of transistor gate widths. A plurality of input CMOS transistors IT1, IT2, are connected in parallel between the nodes and receive input signals at their gates. When any of the input transistors is turned on by a change of input signal state, it conducts between the nodes, causing the input circuit to transition to the active state. An output buffer connected to the nodes translates the node levels to CMOS signal levels.
